I have a used Thinkpad T500. Was used in an automotive shop environment for years. Fully working Windows 7 Pro, recovery partition is gone so I can't restore to original. Still has many years left in it for casual use. Nothing is broken that I can tell, case and screen look good, DVD drive still works. Includes a keyboard cover the key the keys clean. Hasn't been used for a few years, stored in a toolbox. I ran a windows update just to see if anything needs updating. Not sure if it will run Windows 10. That's up to you to try. This thing is heavy, so I don't call it very portable. Works great as a main computer in a confined space!<div><br></div><div>I make no promises to the longevity of this device. It is an older unit. It is currently working as I make this listing.&nbsp;</div><div><br></div><div>Listing price is Firm!</div>
